## Description

dB Meter & Spectrum Analyzer is a Chrome extension that turns your device into a professional sound level meter. It delivers real-time decibel readings with an integrated spectrum analyzer, including octave-band real-time analysis, FFT plots, and a spectrogram, all calibrated using a Nor140 high-precision reference for reliable measurements.

Save measurements with custom names and locations, export data as CSV or audio, and share results. Health app integration supports exporting measured noise levels and audiograms. The tool also includes noise dosimetry aligned with NIOSH and OSHA standards, max/min tracking by frequency, and rich, responsive visuals. Note: it is designed for personal use and not a substitute for professional equipment.

## Review summary

Reviews highlight the app's usefulness as a portable, easy-to-use dB meter with a clear interface and practical use cases. However, repeated concerns about pricing/prompts, ongoing health app integration problems, and stability issues—along with recent updates that limit free usage—dampen overall sentiment.

### Pros

- Very useful for monitoring noise levels and solving real-life sound issues (neighbor complaints, hearing loss, church services).
- Portable and convenient—fits in your pocket or on your wrist.
- Easy to use with a clear, functional interface and calibrated measurements.
- Includes basic tools for noise analysis and generally reliable for everyday use.

### Cons

- Pricing/promo pressure: shifting toward yearly payments or pro subscriptions.
- Persistent prompts to rate/review and to upgrade to pro, even after purchase.
- Health app/HealthKit integration issues (sync problems or access denied).
- Stability issues and bugs (crashes on iPad Pro, recording lag).
- Recent updates restrict free/unlimited use and push for upgrades, reducing prior paid access.
